Starting my TTC Journey soon. Need advice

I’m currently 21 turning 22 next month and me and my partner have been together for just over two years now and we are going to start trying for a baby in the next few days, I’m getting excited just thinking about it. I just recently come off the pill, which I’ve been on for two years as well (could this affect our chances??) and I’m taking folic acid (is this a good thing?) and I went out and bought an ovulation predictor kit and will start testing in the next few days (do these actually work??) but overall I’m excited and terrified at the same time. Any advice would be helpful!! Thanks
